Can't overwrite field timeShift error

[Gabriel T]

Hello

i have a lot of these errors in the logs:

Spoiler: error

09:29:29,684 WARN RestUtils - API-ASYNC-pool-12-thread-3 Can't overwrite field timeShift
java.lang.NoSuchFieldException: timeShift

any idea how to fix it, and what is the impact of performances ?
thank you

Hello,

Please specify the version of the WCS and describe the scenario when the error occurs.

looks like it is happening when using:

Spoiler: Code JS

var participants = _room.getParticipants();
var message = action+"#"+params;
for (var i = 0; i < participants.length; i++) {
participants.sendMessage(message);
}

looks like it is happening when a user join the room, more precisely when issuing rest request to retrieve all strams:

edit: after trying to narrow the source of this error, it appears its not this...but it happens during the connection/joiningRoom process...been trying to call manually all the js functions involved in this process but unable to reproduce it manually...any idea what it could be, maybe if i know with what it is related i can find the responsible function/server call

Good day.
This issue does not affect server perfomance. It concerns obsolete room participants stream recording synchronization feature which was disabled since build 5.2.142.
We raised internal ticket WCS-2444 to fix unused REST hook fields and let you know in this topic.
As workaround, just ignore this exception.

ok many thanks and happy new year !

Good day.
The message java.lang.NoSuchFieldException: timeShift is fixed in build 5.2.789. Please update and check.
